Depending on what features you select, this can create constraints for length, offset, diameter, angle, etc. For instance, there is one button in solidworks called "dimension". Catia tends to be more picky and technical. It's very visual-based (note the number of icons, toolbars, and the design tree). I prefer solidworks to other programs because of it's user-friendliness. These are the features I'm referring to when I say that Solidworks is very POWERFUL. Or you could animate the internal motion of an engine using a section view of the engine assembly. For example, you can animate the assembly of a product (from an exploded orientation, to a fully-constrained orientation.
Solidworks animator can be used in addition to photoworks to create high-quality video animation samples of a moving assembly with proper material appearance. If the part is not molded, you can assign a material to the part, and using a library of hundreds of material properties, Solidworks is able to spit out mass, total volume, strength, and visual properties.įor the models I've shown you above, I've attach a visual material to the surface of the parts and used the Photoworks add-in to get the realistic-looking rendering of the parts in their future material form. At a more advanced level, you can select mold injection points (if you're dealing with a molded part), and solidworks, along with an add-in called Cosmos, will give you an extremely extensive mold-flow analysis, including material strength properties throughout the part. If the part is a welded assembly, you can insert weldment symbols at the joints to create welding instructions very easliy. You don't ever have to draw a single part line. At the most basic level, you can create a model and EXTRACT the drawings (with automatic dimensioning). Soliworks allows you to do infinite things with the model, from that point. But now with 3-D modeling, you can model the entire part and constrain it's geometry using dimensions. It is still used a lot in manufacturing, because it has been "good enough" for so long. AutoCAD is a two-dimensional design program, which is sufficient for designing and printing technical drawings.
